You have two numbers. Do you think you should
add?
subtract?
multiply?
divide?
Divide @Mrs. Sue
Right. So what is your answer.
To find the number of miles Carolina runs per minute, you need to divide the total distance (3 1/2 miles) by the total time (22 1/4 minutes).
First, let's convert the mixed numbers to improper fractions:
3 1/2 = (3 * 2 + 1)/2 = 7/2
22 1/4 = (22 * 4 + 1)/4 = 89/4
Now, divide the total distance by the total time:
7/2 ÷ 89/4
To divide fractions, multiply the first fraction by the reciprocal of the second:
7/2 × 4/89 = (7 × 4)/(2 × 89) = 28/178
Simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 2:
28/178 = (28 ÷ 2)/(178 ÷ 2) = 14/89
Therefore, Carolina runs at a rate of 14/89 miles per minute.
The correct answer is option C.) 14/89 mile per minute.
